Causes of Dizziness

Dizziness is a common condition that can occur alone or as a symptom of another illness. It is a functional impairment of the brain, and the sensation of vertigo can be extremely uncomfortable. If symptoms of dizziness persist, it is essential to seek medical attention, actively investigate the underlying cause, and target treatment to achieve a speedy resolution. Below, we will explore some possible reasons for dizziness.

1. Nervous System Disorders

These include cerebral ischemia, cerebellar lesions, brain lesions, brain trauma, and certain types of epilepsy. Additionally, patients with plantar nerve dysfunction and certain neuroses often experience dizziness.

2. Ear Diseases

Diseases within the ear that affect balance can lead to dizziness.

3. Internal Medicine Conditions

These include hypertension, hypotension, various cardiovascular and cerebrovascular diseases, anemia, infection, poisoning, and hypoglycemia.

4. Cold or Influenza

Occasionally, colds may be accompanied by symptoms of dizziness.

5. Cervical Degeneration

Poor posture or sleeping habits can lead to cervical hyperplasia, deformation, and degeneration. This can cause tightness in the neck muscles, obstructed arterial blood supply, and insufficient brain blood supply, leading to dizziness. Common symptoms include tightness in the neck, limited flexibility, occasional pain, numbness and coldness in the scalp and fingers, shoulder pain, a sense of heaviness, and even accompanying symptoms such as nausea and palpitations.

6. Anemia

If dizziness is accompanied by fatigue and pallor, anemia should be considered. Patients with digestive disorders, peptic ulcers, gastrointestinal bleeding, and chronic inflammatory diseases can develop secondary anemia.

7. Elevated Blood Viscosity

High blood lipids and thrombocytosis can increase blood viscosity, leading to slow blood flow and insufficient brain blood supply. This can cause symptoms such as fatigue, dizziness, and weakness. Currently, the incidence of these diseases is increasing.

8. Cerebral Atherosclerosis

Patients with cerebral atherosclerosis may experience dizziness, frequent insomnia, tinnitus, emotional instability, forgetfulness, and numbness in the limbs. Atherosclerosis narrows the inner diameter of cerebral blood vessels, reducing blood flow and causing insufficient brain blood supply and oxygenation, leading to dizziness. The clinical manifestations include dizziness, sleep disturbances, and memory loss, as well as headache, mild paralysis, speech disorders, and emotional excitability. The condition typically progresses slowly, and dizziness is often exacerbated or appears during changes in body position.

9. Heart Disease and Coronary Heart Disease

In the early stages of these diseases, some individuals may only experience symptoms such as headache, dizziness, weakness in the limbs, difficulty concentrating, tinnitus, or forgetfulness, without significant discomfort such as chest tightness, palpitations, or shortness of breath. Cardiac arrhythmias, paroxysmal tachycardia, paroxysmal atrial fibrillation, and ventricular fibrillation can lead to acute cerebral ischemia, manifesting as dizziness, blurred vision, gastric discomfort, and syncope.

10. Drug Poisoning

Poisoning with drugs such as streptomycin, neomycin, kanamycin, and gentamicin is common. In addition to dizziness, patients may also experience vertigo and sensorineural hearing loss due to cochlear nerve damage. Chronic lead poisoning often manifests as a syndrome of neurasthenia, with dizziness, headache, insomnia, forgetfulness, fatigue, and excessive dreaming as the main symptoms, accompanied by decreased body temperature and loss of appetite.

11. Functional Hypoglycemia

This can cause dizziness, palpitations, and a sense of weakness. Tremors may occur during fasting or exertion, sometimes accompanied by convulsions and loss of consciousness. During emotional stress or hyperventilation, respiratory alkalosis can occur due to increased carbon dioxide excretion, leading to cerebral hypoxia, dizziness, and fatigue. Patients may also experience numbness and a sense of unreality in the face, hands, and feet.

12. Vasodepressor Dizziness

This type of dizziness is often triggered by emotional stress, pain,
